We are preparing to launch patch 2.2.0 on the PTR. You may notice that the PTR is currently available for download in the Battle.net launcher.

At this time, the PTR is not yet live, and you will receive an error if you attempt to log in.

Patch 2.2.0 includes migration to a new file system called CASC (which you can read more about here). As a result, the installation may take longer than you've previously experienced. We're also running additional internal tests before opening up the PTR to the public. Once the the PTR servers are available for testing, we'll update this thread accordingly and post patch notes. Keep an eye on our front page for more information.

We're excited to share our latest patch and thank you for your patience as we make our final preparations.
